"Oh yes, very much so. I've seen it before, not for a long time though. It's not really meant to be seen.
"You may remember the door to Melitus' realm in the factory? That wass a door which did not work like doors normally do. You could not break it down, bypass it, pick the lock. You needed the key. See, most of the Matrix works like the physical world it simulates. But at its base, it's a computer system., It doesn't have to work like that. A door on one side of a wall only connects to the other side because it is programmed thay way by default. That could be changed.
"So most keys are code analogues of real world keys, They just interact, physically, with the simulation of the locking mechanism. But some keys are the representation of something more than that. They go through 'special' doors, doors that otherwise don't work like doors. This is one of those."
"Are you just taking hours to say it unlocks something?" says Dallas. "I can get Ariadne to tell me THAT."
"Smart girl, that one."
"You've not even met her! She's not even from the Matrix!"
"Doesn't stop her being smart," says the Oracle, reasonably. "You're lucky to have her. You're right, though, In any important way, this is still a key. It unlocks a lock. And if you can;t unlock a lock, you might try to find ways around it. If you know how to create the right programme, you might be able to create the code equivlent of a lock pick. or duplicate the key. But some keys cannot be copied, or bypassed. Again, this is one of those.
"There is just one programme in the Matrix who could make a new version of this key. And it so happens that programme works for the people you saw trading this. That's why I thought this might not be real. Maybe the leader of those people- a powerful and dangerous programme, but not one you need to worry about- had it copied and kept it. But he hasn't, this is the original. That says a lot about what he wants. He doesn't want the key."
She sighs.
"But a lot of other people do. You saw what was going on there. Some were willing to trade for it. Some were willing to kill for it. Everyone wanted it. And they still want it, and they won't stop. Won't stop until they have killed you and taken it for themselves."
